The No. 1 1/2 was dropped from the line in 1919, so the gun in question was likely made in the first ten years of Flues production. Most No. 1 1/2 guns had Damascus barrels, with the the 1 1/2 only getting steel barrels the last couple of years it was offered. Early on the No. 1 1/2 had the dog and legend roll-stamped on the sides of the frame with some zig-zag border engraving, then in mid-1915 it got the bold floral engraving. After Ithaca phased out composite barrels the Nos. 1, 1 Special and 1 1/2 were combined in 1919 as the new No. 1 with the bold floral engaving and steel barrels. Throughout this time frame the regular chambering for the Ithaca 20-gauge doubles was 2 1/2 inch. Every cracked frame Flues I've handled has been pre 1920 and a light weight 20- or 28-gauge. IMHO these early very light weight Flues smallbores are a poor choice for a gun to be shot on a regular basis.
